PURULENT KERATITIS

 Purulent keratitis is a type of infectious keratitis, which is an inflammation of the cornea caused by a bacterial or fungal infection. It is characterized by the presence of pus, which is a thick, yellow or greenish fluid that contains white blood cells and microorganisms. Purulent keratitis is a serious condition that can cause significant damage to the cornea, leading to permanent vision loss if not treated promptly and effectively.

Symptoms of Purulent Keratitis

  • Severe pain, redness and light sensitivity in the affected eye
  • Blurred vision or visual distortion
  • Excessive tearing or discharge from the eye
  • The feeling of something in the eye
  • Swelling or cloudiness of the cornea
  • Pus formation on the eye surface or in the cornea

Causes of Purulent Keratitis

  • Bacterial infections such as staphylococcus aureus, streptococcus pneumoniae, haemophilus influenzae, and pseudomonas aeruginosa are the most common cause of purulent keratitis
  • Fungal infections are less common, but can also cause purulent keratitis.
  • Trauma or injury to the eye can also lead to the development of purulent keratitis.
  • contact lens use, specially prolonged use or improper care.

Diagnosis and Treatment

Purulent keratitis is typically diagnosed based on the clinical symptoms and the presence of pus in the cornea. A sample of the discharge or tissue from the cornea may be taken for culture and sensitivity testing to identify the specific cause of the infection.

Treatment of purulent keratitis usually involves the use of topical antibiotics or antifungal medications to eliminate the infection. In some cases, oral antibiotics or antifungal medications may also be prescribed.

To prevent the spread of infection, the eye will be patched with a bandage contact lens to protect the infected area and to help with the administration of the medication.

In severe cases, surgery may be required to remove the infected tissue and to repair the damage to the cornea. In some cases, a corneal transplant may be necessary to restore vision and repair the damage to the cornea.

Prevention and Management

  • Avoiding eye trauma, like rubbing the eyes or exposing them to harsh chemicals
  • Washing your hands frequently, especially before touching your eyes
  • Not sharing personal items such as towels, contact lenses or makeup
  • Following proper contact lens care and replacement schedule
  • Seeking medical attention immediately if you experience any symptoms of keratitis, specially if experiencing eye pain or vision changes

Purulent keratitis can be a serious and sight-threatening condition if not treated promptly and effectively. It is important to be aware of the signs and symptoms of purulent keratitis and to seek medical attention if you experience any symptoms. With proper treatment, most cases of purulent keratitis can be successfully managed and vision loss can be prevented.

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti...

What is myopia?

Image
Myopia is nearsightedness and this condition of eye occurs when the power of eye is increased from the normal powers of eye. The normal powers of eye is 58DS and the eye with >58DS eye power will be marked as myopic eye.  Definition   When parallel light rays coming from the infinity focus Infront of the retina while the accommodation should be at rest this condition of eye is known as myopia.

Scleritis

Scleritis 👌is a painful inflammation (swelling) the sclera. The tough, fibrous tissues of the sclera form a protective outer layer for the eye and make up 83 percent of the eye’s surface. In almost half of all cases, scleritis is associated with an underlying autoimmune disorder such as rheumatoid arthritis. There are two main types of scleritis: anterior and posterior. Anterior scleritis, the most common type, affects the front portion of the sclera. There are three types of anterior scleritis: Diffuse scleritis is the most common type and fortunately the most treatable. This type displays widespread redness and inflammation throughout the whole or a portion of the front portion of the sclera.     Nodular scleritis, is characterized by the presence of nodules , often tender to the touch, on the surface of the eye.     Necrotizing scleritis is the most severe form of anterior scleritis. It has the ability to destroy scleral tissues an...
